Why Choose Our Silicone Rendering Services in South Wales?

Based in Ferndale and proudly serving a 60-mile radius across South Wales and South West England, Global Energy Insulation is your leading PAS 2030 accredited and SWIGA-backed specialist. Our premium silicone rendering and External Wall Insulation (EWI) systems provide the ultimate cold wall treatment—eliminating thermal bridging, stopping cold draughts, and dramatically helping to improve your home's energy efficiency and EPC rating. Plus, working seamlessly alongside our sister company, Global Plastering, we provide a complete end-to-end finish, from robust external weatherproofing to flawless internal traditional plastering.

Why choose our through-colour silicone rendering systems?

Unlike traditional sand and cement renders that require frequent painting, our modern silicone solutions are through-colour, meaning the pigment is integrated into the material itself. This results in a low-maintenance, crack-resistant finish that breathes, preventing moisture from becoming trapped within your walls. By combining these advanced rendering techniques with our expertise in external wall insulation, we help you significantly improve your property's thermal efficiency. This creates a warmer, more comfortable home while simultaneously reducing your monthly energy bills and protecting your masonry from the harsh elements.

How we ensure PAS 2035 compliance and energy efficiency

At Global Energy Insulation, we operate as PAS 2030 compliant specialists with full PAS 2035 retrofit capabilities. For homeowners and landlords in Llanfair-Ym-Muallt and Builth Wells, this means every project is managed with an understanding of whole-house energy performance. We provide essential support for improving EPC ratings, which is particularly vital for landlords needing to meet strict Minimum Energy Efficiency Standards. Our team ensures that all rendering work is not only aesthetically pleasing but also serves as a critical component in your home's long-term energy-efficiency strategy.

FAQ

Frequently Asked Questions

Answers to common questions about our PAS 2030 accredited silicone rendering, weatherproofing, and energy-efficient exterior finishes across South Wales and South West England, South Wales, and the South West.

Why Choose Global Energy Insulation for Your Project?

+

Choosing a contractor is about more than just the price. You need a team that has the right credentials and a track record of quality. We are CHAS accredited and hold a full Waste Carriers Licence, ensuring your property is kept safe and tidy throughout the project.
One of our biggest strengths is our partnership with our sister company, Global Plastering. While Global Energy Insulation handles the external rendering, insulation, and retrofit coordination, Global Plastering provides expert internal plastering. This means we offer a true end-to-end service. We can insulate and render the outside, and then step inside to handle the drylining and finishing, saving you the hassle of managing multiple trades.
Every solid wall insulation project we undertake is backed by a SWIGA (Solid Wall Insulation Guarantee Agency) insurance-backed guarantee, giving you total peace of mind that your investment is protected.

How long does silicone rendering take to finish?

+

Most domestic projects take between 1 and 2 weeks, depending on the size of the house and the weather. We need dry conditions to apply the final thin-coat layer to ensure a perfect, streak-free finish.

Can I apply silicone render over my old render?

+

In some cases, yes, if the original render is structurally sound. However, we usually recommend stripping back to the brickwork or using a base coat with mesh reinforcement to prevent old cracks from showing through the new surface.

Is silicone rendering more expensive than sand and cement?

+

The initial cost is higher because the materials are far more advanced. However, when you factor in that you never have to paint it and it lasts much longer without cracking, it is a far more cost-effective choice for long-term home improvement.

Does silicone render stop damp?

+

Yes. By creating a waterproof, breathable barrier, it prevents driving rain from soaking into your walls, which is a leading cause of penetrating damp in South Wales homes.
